Hi,
I have a registered node like the following --
VLIB_REGISTER_NODE (MyNode) = {
.name = "MyNode",
.
.
.n_next_nodes =N,
.next_nodes = {
[firstone] = "error-drop",
[secondone] = "ip4-lookup",
[thirdone] = "ip6-lookup",
[fourthone] = "may-or-may-not-be-loaded-node",
.
.
Now I want to be able to run the system whether the fourth one above
is loaded or not as a .so
The business logic in my code takes care that I never use the fourth
one in case it is not loaded. I have a private configuration which
tells me whether the fourth one is present in deployment or not.
But the VLIB_REGISTER_NODE requires the wiring at compile time like the above.
And the system will not startup if the fourth one is not actually
present in deployment
So I want to avoid mentioning the fourth one in the VLIB_REGISTER_NODE
of MyNode as one of the next_nodes.
And then how to add it as one of the next_nodes from runtime for
MyNode when my private configuration tells me that the fourthone
indeed is existing in the deployment ? I am looking for some API to
wink in the fourth one at runtime into .next_nodes of MyNode.
Regards
